Eberspächer develops air cleaning system for bus and coach applications
By Jim Gibbins - 11th March 2021
Germany - Thermal management specialist, Eberspächer Climate Control Systems GmbH of Esslingen has developed a three-step-solution to provide clean air inside city buses and coaches. The system uses particulate filters for air filtration, a Polarised Media Electronic Air Cleaner in the bus AC system, which captures contaminated water droplets and UV-C LED modules for inactivating viruses.
The particulate filter is a pleated-type filter fitted adjacent to the evaporator coil, replacing the existing polyurethane foam filter for a low to medium filtration level. In addition to dust, pollen, mould, and soot, these filters will also collect water droplets which contain viruses distributed by aerosol transmission. Water droplets vary in size from 0,6 µ to 10 µ: Eberspächer Particulate Filters can trap up to 74% of particles size 0,5 µ and up to 90% of particles size 10 µ. The filters are installed within the roof-mounted air-conditioning system.
